Let’s talk vision issues. Anyone?

I noticed when my ferritin drops below 40 I experience the following vision issues:

Wavy vision- this is like looking at a still object (like the frame of a white door) and it shakes ever so slightly- almost like looking through a “heat haze”. Or if I look at a curtain against a window it almost looks “flickering” or shaky.

Blurry vision. Not blurry enough to be dangerous but enough to be annoying. Vision just doesn’t feel as crisp and clear.

Floaters, flashes and circles of light. Had ophthalmology appointment and everything is technically “ok”, but I get these visual disturbances regardless.

Does anyone experience wavy “heat haze vision”, blurry unclear vision, or flashes and floaters when more anemic?

This is one of the fewer symptoms I see talked about so wanted to compare notes.

Hemoglobin is 11.4 and ferritin is 35. Both are low and I’m working on supplementing high dose elemental iron at the moment.

Other symptoms are brain fog - feeling like I’m on DayQuil or something, even though I don’t take any medications. Also fatigue and the vision issues. Occasional balance and dizzy, drunk like feeling.

Aside from the anemia I’m otherwise super healthy, so it really sets me back.
